Intel Panther Lake-H & Panther Lake-U CPU Configurations Revealed: Up To 16 CPU Cores, 12 Xe3 “Celestial” iGPU Cores, Five Tiles In 25W Flavors

Intel’s next-gen Panther Lake CPU configurations have been unveiled, showcasing up to five tiles and significant advancements in processing power and efficiency.

Key Features of Intel Panther Lake CPUs

Five Tiles, Three Active: The Panther Lake CPUs will feature five tiles, with only three being active. These include the compute tile, the Platform Controller Die (PCD), and the Graphics (Xe3) tile. The remaining two tiles are passive, contributing to the chip’s rectangular shape.

High-End and Entry-Level Options: The Panther Lake lineup includes the high-end Panther Lake-H and the entry-level Panther Lake-U, set to replace the Arrow Lake-H and Arrow Lake-U CPUs. These CPUs will cater to a wide range of laptop platforms, from thin and light to high-end models.

Advanced Core Configurations:

Panther Lake-H: Up to 16 CPU cores, including 4 P-Cores (Cougar Cove), 8 E-Cores (Darkmont), and 4 LP-E cores. The iGPU will feature either 12 or 4 Xe3 cores, utilizing the Celestial graphics architecture. The TDP is set at 25W (PL1) and 45W (PL2).
Panther Lake-U: Designed for thin and light laptops, this series will have 4 P-Cores and 4 LP-E cores, totaling 8 cores. The iGPU will include 4 Xe3 cores, with a TDP of 15W (PL1) and an estimated 28-30W (PL2).

Production and Availability

Intel has confirmed that the Panther Lake CPUs have achieved “Power On” status and will enter production on the 18A process node in the first half of 2025. Availability is planned for the second half of 2025.

Detailed Blueprint Insights

The blueprint for the Panther Lake-H CPU reveals the following tile sizes:

Compute Tile (Die 4): 8.004 x 14.288 mm (114.3 mm²)
Platform Tile (Die 1): 12.408 x 3.953 mm (49.048 mm²)
Graphics Tile (Die 5): 8.097 x 6.76 mm (54.73 mm²)
Passive Tiles (Die 2 and Die 3): 6.112 x 3.592 mm (24.154 mm²) and 3.952 x 2.489 mm (9.83 mm²)

The total size of the Panther Lake-H CPU is approximately 274.2 mm², slightly larger than the Meteor Lake CPUs.

Future Prospects

Intel’s Panther Lake CPUs are expected to offer greater flexibility and higher memory capacities on thin and light platforms compared to Lunar Lake. More details are anticipated at Intel’s Innovation event in September.
